A new way of designing auxetic materials

Imagine pulling on the long ends of a rectangular piece of rubber. It should become narrower and thinner. But what if it instead became wider and fatter? Now, push in on those same ends. What if the rubber became narrower ...

Researchers develop entangled photon pairs in integrated silicon carbide for first time

Quantum information science is truly fascinating—pairs of tiny particles can be entangled such that an operation on either one will affect them both even if they are physically separated. A seemingly magical process called ...

The interference of many atoms, and a new approach to boson sampling

In daily life, when two objects are "indistinguishable," it's due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep track of which ball is which as they are ...

Twisting and binding matter waves with photons in a cavity

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it ...
